Hi, Thanks for posting in HCM. I understand your concern. What problems you are facing with reference to premature ejaculation and erectile dysfunction is more of psychological problem than physical. What medication has been prescribed like Jakjoy, which is a multivitamin and Tadalafil, which improves blood supply to penis to sustain erection, would help you to achieve good erection. For premature ejaculation, you need to practice behavioral technique like pause and squeeze technique along with use of local anaesthetic spray to decrease sensation. Slowly, over a period of time, you would gain confidence and can overcome the problem and reduce the medications and take it only when it is really necessary. You can also practice meditation to keep your mind calm and spend more time during foreplay to increase your confidence. Hope the information provided would be helpful. All the best.
